FUJIFILM Corporation (President: Kenji Sukeno) has announced that it will release the “FUJINON LENS GF250mmF4 R LM OIS WR” lens for the Medium Format GFX system in May 2018. This lens is the first telephoto lens for GF lens series. It realizes high-resolution and rich bokeh by utilizing technologies applied in FUJINON Lenses, which are widely used in cinema and broadcast industry. It is ideal for shooting highly defined portrait, as well as landscape which emphasizes the model. Simultaneously, the company will release “FUJINON Teleconverter GF1.4X TC WR” to extend the focal length by 1.4 times, and the macro extension tubes “MCEX-18G” and “MCEX-45G” to expand the range of macro photography.

GF Lenses are exchangeable lenses for GFX Series medium format mirrorless digital cameras with large sensors (43.8×32.9mm). They are Fujifilm's highest-grade lenses realizing high precision lens surface accuracy, and utilize Fujifilm's superior optical design technology and production technology in order to achieve high-resolution and rich tone reproduction. The GF250mmF4 R LM OIS WR realizes the highest image quality with medium format sized sensors, an area approximately 1.7 times larger than 35mm format, in combination with Fujifilm's unique color reproduction technology. Fujifilm has already released the “FUJIFILM GFX 50S”, the first camera in the “GFX Series,” as well as six “GF Lenses”. All of which have proved popular among professional photographers and photo enthusiasts, who praise the system for its ability to capture high levels of detail, giving the atmosphere a three-dimensional feel, and its compact, lightweight body for easy operation.

The GF250mmF4 R LM OIS WR is a telephoto lens that achieves approximately 198mm in 35mm format equivalent, bringing together Fujifilm's proprietary optical design technology and offers high resolving power for supporting further enhancement of image resolution in the future. The lens is capable of capturing the atmosphere of any scene through a combination of high-resolution performance and rich bokeh effect. Attaching the “GF1.4X TC WR”, a 1.4x teleconverter provides coverage for telephoto shooting up to approximately 277mm in 35mm format equivalent without any image quality deterioration. The lens is also equipped with the new focus pre-set function, which allows the photographer to instantly activate focus settings previously saved in the lens memory. The use of a magnesium alloy lens barrel reduces the product's weight. In addition, the lens is dust and weather resistant and capable of operating in temperatures down to -10°C, ensuring that this new lens will serve as a trusted partner for professional photographers.

Thanks to the launch of new lenses “FUJINON LENS GF250mmF4 R LM OIS WR” and “FUJINON Teleconverter GF1.4X TC WR”, seventh and eighth lenses in the GF lens series, the shooting range of the GFX exchangeable lens system will greatly expand in the telephoto range. In addition, the macro extension tubes “MCEX-18G” and “MCEX-45”, which will be released simultaneously, can be connected to any GF lenses, expanding the macro photographic range. Photographers can be satisfied with GFX Series products with a new, expanded shooting range, offering more opportunities for photography.

1. Main Features

＜Telephoto lens GF250mmF4 R LM OIS WR＞

(1) Ultra-High Image Quality The lens is composed of 16 lenses in 10 groups including one super ED lens and two ED lenses, reducing chromatic aberration and achieving excellent image quality. Especially, super ED lens is used to reduces the fluctuations in chromatic aberration depend on the shooting distance. It enables to shoot minimum 1.4m close focus, maximum 0.22 x magnification ratio, and tele-macro shots with large bokeh effects.

(2) Strong Image Stabilization The lens is equipped with a powerful five-stop image stabilization function (CIPA guidelines). This allows photographers to make maximum performance of the GFX's high image resolution even when taking telephoto shots where image shake might be obvious.

(3) Various Functions The lens’ functionality includes a focus range selector to enable faster autofocus speed by restricting focus range, focus pre-set function for memorizing focus settings previously set into the lens, and the focus control button located at the lens front to enable focus lock or autofocus.

* An upgrade of the GFX50S firmware is required to operate the focus pre-set function and focus control buttons. This functionality is included in the new version of the GFX50S firmware that will be released at the same time.

(4) Silent and High-Speed Autofocus The linear motor which drives the focus lenses achieves high-precision, silent, and fast autofocus operation. In addition, the lens also includes a new mechanism for fixing the linear motor position when turning the power off or playback to avoid unnecessary vibration.

(5) Robust Design Appropriate for Various Tough Shooting Environments The lens barrel is made with a magnesium alloy, ensuring both robust structural integrity and a light weight. Sealing has been applied to the lens in 18 different locations for dust and weather resistance and the ability to operate at temperatures of down to -10°C. A fluorine coating is also applied to the front lens element to repel water and dirt under tough outdoor situations.

＜Macro Extension Tube＞ Fujifilm has developed 18mm and 45mm macro extension tubes (MCEX-18G WR, MCEX-45G WR), expanding the range of macro photography. Connecting the macro extension tubes to any GF lens allows macro photographs to be taken at a higher magnification ratio. For example, connecting the GF120mmF4 R LM OIS WR Macro (half-macro) and the MCEX-45G makes it possible to take photographs with life size 1:1 macro.
